geometry
Principal, Gaussian, and mean curvature, developed for potatoes embedded in three-space.
A week-long class from Mathcamp 2018 about the principal, Gaussian, and mean curvature of potatoes embedded in \(\mathbb{R}^3\).
The prerequisites are linear algebra (in particular eigenvalues and eigenvectors) and multivariable calculus.
